JpGraph and PDF

[iulian.ilea]

Hi,

I use JpGraph to generate some graphs and I have to include those
graphs in a pdf file, generated usign fPDF (http://www.fpdf.org/). If I
include a png file it's ok, the pdf file is generated, everithing goes
ok. If I use this code:
___
$logo=file_get_contents('splineex1.php');
//Output it (requires PHP>=4.3.2 and FPDF>=1.52)
$pdf->Image('var://logo', 0, 0, 150, 0, 'PNG');
___

....to include genereted graph i get this error:
___
CGI Error
The specified CGI application misbehaved by not returning a complete
set of HTTP headers. The headers it did return are:
___

So, I need to save generated graph into a file and then to include in
pdf using
___
$logo=file_get_contents('splineex1.png');
//Output it (requires PHP>=4.3.2 and FPDF>=1.52)
$pdf->Image('var://logo', 0, 0, 150, 0, 'PNG');
___

The problem is that I can't find how to save it.

I made it work using a trick, but I hope I'll find another solution. If
you have any ideaa... post it.

trick:
I use IIS. I created one virtual directory with a name... example (in
my cased). After, I renamed the php script in scriptphp.png (i changed
the extension to png) and from Virtual Directory tab in Internet
Information Server, click Configuration, add new extension - png - and
set it to be executed by php.

Now, if I use:
___
$pdf->Image("http://localhost/examples/scriptphp.png", 0, 0, 150, 0,
'PNG');
___

....it works.

I tried with curl too, but is not working. Or I can't make it work.

If you do this, $logo will contain your PHP code. To get the image,
you need to do:

$logo = file_get_contents('http://localhost/path/splineex1.php');

So, I need to save generated graph into a file

You could, but you don't have to (see above). If you still want to
save the image into a file, you can do it inside splineex1.php by
specifying the target file name as a second argument to imagepng().
See imagepng() dicumentation:

http://www.php.net/imagepng

Alternatively, you could do:

$logo = file_get_contents('http://localhost/path/splineex1.php');
$fp = fopen('splineex1.png', 'w');
fwrite($fp, $logo);
fclose($fp);
